8-4 Project Part Two Presentation

5. The car you have been driving has a posted fuel consumption of 10.0 L/100 km (city) and 7.1 L/100 km (highway) according to the EnerGuide information. Overall, your actual fuel consumption has averaged 10.5 L/100 km. a) Is this better or worse than the posted fuel consumption? b) Provide three reasons why your actual fuel consumption may be different from the posted consumption. c) List three ways in which you could improve your fuel consumption (other than buying a new carl).

Paragraph 5: Discuss Fractional Distillation of petroleum oil to give the chemical feedstock to make synthetic polymers for commercial use of products in our daily lives and discuss your personal thoughts on incresing US drilling in the Gulf of Mexico or in the Artic. Think about it, every time you go to the grocery store and get a plastic bag which immediately gets discarded. Include your thoughts on mandatory recycling in the US especially for schools, government buildings, etc.

The life cycle of a plastic bottle After reading the text below, answer the following questions. Make sure to put it in your own words. This is the story of three plastic bottles, empty and discarded. Their journeys are about to diverge with outcomes that impact nothing less than the fate of the planet. But they weren't always this way. To understand where these bottles end up, we must first explore their origins. The heroes of our story were conceived in this oil refinery. The plastic in their bodies was formed by chemically bonding oil and gas molecules together to make monomers. In turn, these monomers were bonded into long polymer chains to make plastic in the form of millions of pellets. Those were melted at manufacturing plants and reformed in molds to create the resilient material that makes up the triplets' bodies. Machines filled the bottles with sweet bubbly liquid and they were then wrapped, shipped, bought, opened, consumed and unceremoniously discarded. And now here they…

Which one is it?

When we think about the carbon cycle and human activities, it is important to differentiate between facts and hypotheses. Which of the answer choices can be considered a fact? Select all that apply. Increasing atmospheric carbon dioxide will cause mean global temperature to increase by 2 degrees Celsius over the next century. In the past, atmospheric CO₂ levels rose higher than those observed today. The burning of fossil fuels contributes substantially to the ongoing rise of atmospheric CO2- The amount of carbon dioxide in the atmosphere has increased since 1950.

A student is preparing a solution of sucrose at a specific concentration. They are doing this by weighing out sucrose on a scale, placing it in a volumetric flask, dissolving it in water, and then diluting it up to the mark on the volumetric flask with water. How would the experimental (actual) molar concentration for C12H22O11 differ from the calculated concentration ( higher, lower, or the same) given the following scenarios? Explain.
